Operator's guide
The distance between the cursors is given in the text of the Time
Cursors or Ampl Cursors icon, in seconds and Hz or counts. You can
have both vertical and horizontal cursors active at the same time.
Because the limit of accuracy of the cursors is one pixel, you should
zoom in to the range of interest before measuring.
The Ampl Cursors measure distances in counts according to the
current zoom settings. However, if you have applied a scaling factor to
an individual stream (see below), the Ampl Cursors do not take this
scaling into account. If you set a stream's scale factor to the combined
sensitivities of the sensor and digitizer, you can set up the window so
that one pixel corresponds to a useful value in physical units.
To obtain the true value in counts, divide the value displayed in the
Ampl Cursors icon by the scale factor for that stream, as displayed
beneath its ID on the left-hand panel.
3.6.3 Printing
To print the data currently being displayed in the Waveview window,
click on the Print icon
. Scream! will use the current printer
settings to print a full page view of the window, using the current
amplitude and time scaling, filtering and other display options. You
can print at any time, in either real-time or paused mode.
To print the same data in black and white (on a colour or greyscale
printer), click on the arrow beside the Print icon and select Page Print
(monochrome) from the drop-down menu. Black and white output is
more suitable for copying or faxing.
